BACKGROUND OF THE INVENTION
The present invention relates to a toilet apparatus provided with an air conditioner that cools or heats a toilet room or the like in a flush toilet that flushes and flushes toilets.
[0002]
[Prior art]
The air conditioner provided in the conventional flush toilet apparatus has a configuration as shown in FIG. That is, the air conditioner having the compressor 31, the condenser 32, the evaporator 33, and the like constituting the refrigeration cycle is provided with the condenser 32 on the wall across the corner of the toilet room 34, and stores water for washing the toilet 35. The compressor 31, the evaporator 33, the blower fan 37, etc. are placed in one case 38 and installed on the wall of the toilet room 34.
[0003]
Then, the refrigerant is circulated with the condenser 32, the evaporator 33, and the compressor 31 by the operation of the compressor 31, and the air in the toilet room 34 is heat-exchanged by the evaporator 33 by the blower fan 37, and the toilet room 34 is discharged from the outlet 39. The cooling air is sent to the air-conditioner, and the condensation heat of the condenser 32 is radiated to the water in the water tank 36 and is not released into the toilet room 34.
[0004]
The water tank 36 is provided with an electromagnetic valve 41 in a passage 40 for guiding the hot water heated by the condensation heat to the toilet bowl 35, and the electromagnetic wave is detected based on a detection signal of a temperature detector 42 for detecting the water temperature of the water tank 36. It was the structure which controls the opening / closing frequency of the valve 41 more or less. In the figure, 43 is a toilet seat.
[0005]
[Problems to be solved by the invention]
In the conventional toilet air conditioner, since the condenser 32 is submerged in the water tank 36, maintenance becomes difficult, and the compressor 31, the evaporator 33, the blower fan 37, etc. are provided in the case 38. In addition, the condenser 32 is separately attached to the water tank 36 on the wall, so that the entire apparatus is not organized, and installation work in the toilet room 34 is troublesome, and the effective space of the toilet room 34 is further narrowed.
[0006]
During the air conditioning operation, the water in the water tank 36 is heated by condensation heat until the electromagnetic valve 41 is opened based on the detection signal from the temperature detector 42 and flows out to the toilet 35 through the passage 40. As a result, the temperature rises relatively quickly, and an upper and lower temperature distribution is generated in the water tank 36. The heat radiation action of the condenser 32 is reduced in a short time, and the cooling capacity may be lowered. The water inside was drained through the passage 40, which was uneconomical.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter per toilet apparatus definitive to an embodiment of the present invention will be described with reference to the drawings.
[0017]
(Embodiment 1)
Figure 1 is a constitutional view showing by cutting out the front main part of the definitive toilet device according to an embodiment of the present invention, FIG. 2 is a schematic perspective view showing by cutting out the front main part of the toilet apparatus. The air conditioner that cools the toilet room 1 has a compressor 2, a condenser 3, a decompressor 4, an evaporator 5 of a finned tube heat exchanger, etc. that constitute the refrigeration cycle, and further circulates the air in the toilet room 1. A control unit 7 mainly composed of a blower fan 6 that exchanges heat with the evaporator 5 and a microcomputer that controls the cooling operation by wiring to the blower fan 6 and the compressor 2 is added.
[0018]
Such an air conditioner has a vertically long and thin flat water tank 12 (low tank) having a floating 10-type automatic water supply valve 11 that stores flush water flowing to the toilet 8 and washing it up to a full water surface 9. And a heat exchange means 14 connected to the upper portion to form a circulating water circuit 13 and coupled to the condenser 3 so as to be capable of exchanging heat, a pump 15 provided in the circulating water circuit 13 for circulating wash water, and a compressor 2, a condenser 3, an evaporator 5, a blower fan 6, etc. are provided on the outer side of the water tank 12, and a substrate of the control means 7 is provided close to the lower front surface of the water tank 12. The components of the water tank 12 and the air conditioner that are arranged in a compact manner are covered with a single flat case 16, and are further provided upright integrally with the rear portion of the toilet seat 17 provided in the toilet bowl 8. Installed on.
[0019]
The condenser 3 and the heat exchanging means 14 are a double pipe heat exchanger having a high heat exchange rate and capable of being miniaturized, or a flow path through which washing water flows between the plates by laminating a plurality of plates. A plate laminated heat exchanger having a flow path through which the refrigerant of the refrigeration cycle is formed is used. In this example, a double pipe heat exchanger comprising an outer pipe 14a through which water passes and an inner pipe 3a through which the refrigerant of the refrigeration cycle passes is used. I use it.
[0020]
The pump 15 is connected to the lower part of the water tank 12 at a position lower than the full water surface 9 of the circulating water circuit 13 and the lower part of the outer pipe 14a of the heat exchange means 14 via two-way switching valves 18 and 19, respectively. Then, water is sucked from the lower part of the water tank 12, and the water is circulated through the circulating water circuit 13 in the order of the upper part of the water tank 12 through the heat exchanging means 14. The pump 15 and the two-way switching valves 18 and 19 are connected to the control means 7, and the pump 15 is started in response to an instruction from the control means 7 that receives a signal based on the operation of the air conditioner operation. 18,19 Ri exchange switching to the circulating water circuit 13 side, the pump 15 is stopped at the stop of the operation.
[0021]
The local cleaning device 20 warms the cleaning water ejected from the local cleaning nozzle 21 by the pump 15, the local cleaning nozzle 21 that injects hot water to the local area, the pump 15 that sends the hot water for cleaning to the local cleaning nozzle 21, and the like. A heater 22 such as electricity is provided, and the case 16 is disposed in a horizontally long manner integrally with the toilet seat 17 at the lower front portion of the case 16. Of course, the case 16 may be covered together with the air conditioner, the water tank 12 and the like. Since the local cleaning device 20 shares the pump 15 of the circulating water circuit 13 in order to reduce the number of parts and make it compact as described above, one passage of the two-way switching valve 19 on the suction side of the pump 15 is used. Is connected to a pipe 23 leading to the water pipe of the local cleaning device 20, and one passage of the two-way switching valve 18 on the discharge side of the pump 15 is connected to the local cleaning nozzle 21.
[0022]
As described above, since the pump 15 of the circulating water circuit 13 is used both when the air conditioner is in operation and when the local cleaning device 20 is used, the control means 7 receives a signal indicating the operation of using the local cleaning device 20. Then, an instruction signal for temporarily interrupting the operation of the air conditioner that has received the instruction is issued, and the two-way switching valves 18, 19 from the circulating water circuit 13 side based on the priority operation signal of the local cleaning device 20 Is switched to the local cleaning device 20 side, and the pump 15 is started, the hot water warmed by the heater 22 is ejected from the local cleaning nozzle 21, and when the signal for the end of the local cleaning is received, the two-way switching valves 18, 19 are reactivated. The pump 15 is controlled so as to return to the original operating state of the air conditioner, and is executed by executing a program storing the control flow described above. In consideration of the short usage time of the local cleaning device 20, the temporary interruption of the operation of the air conditioner described above stops the operation of the compressor 2 and stops the circulation of the refrigerant. The heat that is stored cold is used effectively.
[0023]
As an example, 24 is an inlet provided at the lower side of the case 16, and 25 is an outlet provided at the left and right ends of the upper part of the front of the case 16, and conditioned air is delivered to the neck of an adult user sitting on the toilet seat 17. It is designed to blow out. Further, a deodorizing device (not shown) is added at the optimum position of the flow path from the intake port 24 to the blowout port 25. A valve seat lid 26 is provided on the toilet seat 17 so as to be freely opened and closed. The toilet seat 17 is provided with a heater (not shown) for heating.
[0024]
Reference numeral 27 denotes a blower guide of the blower fan 6, which leads to the blowout port 25. 28 is a drainage passage through which the washing water passes, in order to flow a large amount of washing water from the water tank 12 to the toilet bowl 8 at a time, and to wash and wash the toilet bowl 8. A water stop valve 29 is provided. Accordingly, in the water tank 12 in which a large amount of washing water has flowed from the drainage channel 28, tap water is replenished from the automatic water supply valve 11 operated by the float 10 to the full water surface 9 when the water level drops below the full water surface 9, and thereafter. This operation is repeated. The arrows in the figure indicate the flow of air, water, and refrigerant.
[0025]
In the above embodiment, when the air conditioner is operated with a switch or the like before or after entering the toilet room 1, the control means 7 starts control. That is, the refrigerant circulates in the order of the compressor 2, the condenser 3, the decompressor 4, the evaporator 5, and the compressor 2, and the pump 15 is started by the control means 7 that receives the instruction signal for operating the air conditioner. The switching valves 18 and 19 are switched to the circulating water circuit 13 side, water having a low water temperature at the bottom in the water tank 12 is sucked into the pump 15 and flows to the heat exchanging means 14, and the full water surface at the top of the water tank 12 9 circulates in the circulating water circuit 13 returning to 9, and a flow of water always occurs in the heat exchanging means 16, and the wash water in the water tank 12 also averages the water temperature distribution over the course of the circulating water flow and changes uniformly.
[0026]
Therefore, the condenser 3 can actively dissipate the heat of condensation in the low-temperature water in the lower part of the water tank 12 that constantly circulates, and can exchange heat with the heat exchanging means 16. Maintains stable heat dissipation with wash water with uniform water temperature distribution.
[0027]
On the other hand, the air in the toilet room 1 is sucked into the case 16 from the air inlet 24 by the rotation of the blower fan 6, deodorized through the deodorizing device, cooled by the evaporator 5, and cold air is blown from the outlet 25. Blow out and air-condition the vicinity of the user's neck and toilet room 1 in the toilet seated on the toilet seat 17.
[0028]
After the flight, the operation of the local cleaning device 20 is operated with a switch, and the control means 7 receiving this instruction signal temporarily operates the air conditioner in preference to the instruction signal of the air conditioner operation so far. Stop (the operation stop of the air conditioner mentioned above may stop all the air conditioning functions including the compressor 2 or continue the operation of only the compressor 2 to prevent the compressor 2 from waiting for restart. The functions other than the compressor 2 may be stopped, and the two-way switching valves 18 and 19 are switched from the circulating water circuit 13 side to the local cleaning device 20 side. Then, the hot water warmed by the heater 22 when the pump 15 is started is sprayed from the local cleaning nozzle 21 to clean the local area. After that, the control means 7 that has received the instruction signal for ending the local cleaning determines that the operation of the air conditioner that has been temporarily suspended is returned to, and controls the operation of the air conditioner again.
[0029]
On the other hand, the control means 7 receiving the operation signal of the switch for discharging the waste and washing the toilet bowl 8 opens the water stop valve 29, and a large amount of washing water from the water tank 12 passes through the drainage channel 28 to the toilet bowl 8 at a time. Flowing filth is discharged and the toilet bowl 8 is washed. When a large amount of washing water has finished flowing from the water tank 12 to the toilet bowl 8, the control means 7 closes the water stop means 16. Of course, in the water tank 12, when the water level drops from the full water surface 9 to a predetermined position, the automatic water supply valve 11 with the float 10 opens, new water is replenished from the water pipe to the full water surface 9, and the water supply is stopped. Is repeated.
[0030]
As described above, in the present embodiment, the pump 15 started by the operation of the air conditioner by the control means 7 circulates the wash water in the water tank 12 to the circulating water circuit 13, so that the water temperature distribution in the water tank 12 is The condenser 3 can be uniformly exchanged with the heat exchange means 14 by the water having a uniform temperature that is constantly circulated and the heat can be efficiently exchanged, and the capacity of the air conditioner can be prevented from being lowered. Because it is reused, a water saving effect is also obtained.
[0031]
The air conditioner and heat exchanging means 16 and the pump 15 are arranged on the outer side of the water tank 12, the control means 7 is arranged close to the front surface of the water tank 12, and these organically combined water is arranged. The components of the tank 12 and the air conditioner are covered with one flat case 16 so as to be integrally provided upright on the rear part of the toilet seat 17 and attached to the rear end part of the toilet bowl 8, so that the entire apparatus can be made compact. In addition, the effective space of the toilet room 1 can be secured, and the installation work at the site including the power supply and piping, that is, the toilet room 1 where it is generally difficult to secure a large space is much easier than the conventional one. Will be possible.
[0032]
Further, in the present embodiment, the pump 15 is connected to the lower side of the water tank 12 via the two-way switching valve 19 and the discharge side to the heat exchanging means 16 via the two-way switching valve 18 and further to heat. Since the exchange means 16 is communicated with the upper part of the water tank 12 to form the circulating water circuit 13, the water is circulated in order from the lower part of the water tank 12 to the upper part of the water tank 12 via the heat exchange means. The pump 15 started by the operation of the air conditioner by means 7 is always sucked from the low temperature water in the lower part of the water tank 12 and sent to the heat exchanging means 14, and the water whose temperature has risen by exchanging heat with the condenser 3 is The circulating flow sent to the upper part of the tank 12 is caused, and the heat of the condenser 3 is always radiated to water having a low temperature as a whole, so that the heat can be radiated with high efficiency and the deterioration of the capacity of the condenser can be prevented.
[0033]
In the present embodiment, since the pump 15 is disposed at a position lower than the full water surface 9 of the water tank 12, there is always a priming water for starting, and the starting can always be facilitated.
[0034]
In this embodiment, the pump 15 is connected to the lower side of the water tank 12 and the pipe 23 of the local cleaning device 20 via the two-way switching valve 19 on the suction side, and the heat exchange means 16 and the local cleaning nozzle 21 on the discharge side. Are connected to each other via the two-way switching valve 18 and are switched by the control means 7 between the local cleaning device 20 side and the circulating water circuit 13 side of the air conditioner so that the pump 15 can be shared.

Further, in the present embodiment, the heat exchange means 14 and the condenser 3 are a double-pipe heat exchanger composed of an inner tube 3a and an outer tube 14a, or a flow of cleaning water between the plates by laminating a plurality of plates. Since it can be composed of a plate-stacked heat exchanger having a passage and a flow path through which the refrigerant of the refrigeration cycle flows, highly efficient heat exchange and downsizing can be achieved.
[0036]
In the above embodiment, when the local cleaning device 20 is used, the circulation of the refrigerant in the refrigeration cycle is stopped and the blower fan 6 is moved by temporarily interrupting the operation of the air conditioner. Only the heat exchanging action on the condenser 3 by the heat exchanging means 14 may be stopped.
[0037]
In the above embodiment, a well-known refrigeration cycle system is used as the air conditioner. However, a Peltier effect type electronic cooling element may be used. In this case, the heat radiating side of the electronic cooling element is heated instead of the condenser 3. The water in the exchange means 14 is brought into contact. In the above embodiment, the air conditioner cools the toilet room 1, but it is also possible to perform heating by reversing the circulation of the refrigerant in the heat pump refrigeration cycle as compared with that during cooling. Furthermore, in the above-described embodiment, the air inlet of the air conditioner is provided on the side surface of the case 16 as an example. However, the present invention is not limited to this, and gaps between the case 16 and the case 16 generated when the case 16 is attached to a toilet seat or the like.
